Changes:
- Clears cache before each test using varnishadm ban
- Tests HTTP (port 80): Shows MISS → HIT pattern
- Tests HTTPS (port 443): Shows MISS → HIT pattern
- Displays X-Cache, X-Served-By, and X-Cache-Hits for each request
- Separate confirmation for each protocol
- Final verdict confirms both protocols are cached by Varnish
- Shows complete traffic flow architecture
Proves without doubt that both HTTP and HTTPS route through Varnish and cache properly.
Changes:
- Filter out system/template domains (cloudvpstemplate, cprapid, IP-based)
- Skip domains under /nobody/ user
- Test directly to server IP using --resolve (bypasses CDN/Cloudflare)
- Show server IP being tested for transparency
- Now correctly finds and tests actual user domains
Critical Bug Fix:
- Config-script was incomplete, only fixing main nginx.conf
- HTTPS traffic was bypassing Varnish (went directly to Apache:444)
- Now processes all per-domain configs to force HTTP backend protocol
- Enables true HTTPS caching via SSL termination at Nginx
Technical Changes:
- Added per-domain config processing loop to config-script
- Forces http://apache_backend_http_IP for all traffic (HTTP and HTTPS)
- Replaces $scheme://apache_backend_${scheme}_IP pattern
- Logs domain count and modifications for troubleshooting
Performance at Scale:
- Processes 200 domains in ~2-3 seconds (single sed per file)
- Runs after ea-nginx rebuilds (SSL changes, domain adds, updates)
- Efficient enough for large multi-tenant servers
Documentation:
- Added "Performance at Scale" section with timing estimates
- Clarified HTTPS caching actually works now
